Monitoring the Access Point LEDs
If your access point is not working properly, look at the LEDs on the bottom of the unit. You can use
them to quickly assess the status of the unit.
Note It is expected that there will be small variations in LED color intensity and hue from unit to unit. This is
within the normal range of the LED manufacturer specifications and is not a defect.
The access point LED signals are listed in Table 3-1.
